Oil condensing technology
What is a condensing boiler?
Award winning technology
Condensing boilers are designed to capture heat normally lost through the flue system during the combustion process.
Grant has become synonymous with highly efficient oilfired central heating appliances which help thousands of homeowners to reduce their annual fuel bills. Our ‘Multi Pass’ boiler achieves efficiency levels far in excess of any UK or European Standards while our Vortex oil-fired condensing boilers top the Government SEBUK Efficiency Database and are the market leading product in this sector.
Unlike traditional oil-fired boilers the Grant Vortex condensing boiler has a built-in stainless steel heat exchanger incorporating our unique turbulator baffle system which cools the gases to a point where the latent heat, normally lost to the atmosphere through the flue, can be usefully extracted. The additional energy recovered enables the boiler to operate continuously at much higher efficiency levels, resulting in lower heating and hot water running costs.
We have received numerous prestigious and high profile awards in recognition of our innovative product design, high quality engineering and exceptional training. • Product of the Year 2008 (Grant Vortex range) H&V News Awards for Excellence
• Which? Best Buy Accreditation 2008 (Grant Vortex Combi Pro 26)
The benefits of Grant Vortex While older oil-fired boilers operate with energy efficiency levels as low as 65%, modern boilers operate with much higher efficiency. The Grant Vortex range has the highest energy efficiency rating in the UK which not only significantly lowers fuel bills but also considerably reduces greenhouse gas emissions and lessens the environmental impact of domestic hot water and heating systems. All Grant Vortex boilers are easy to install and can either be connected to a conventional ‘stainless steel’ flue or one of Grant’s EZ-Fit flue options using an existing chimney.

Grant Vortex Eco External range
Introduction
Dimensions (mm)
Grant developed the first oil-fired external boiler in 1986 and although the concept was new to the oil market, it quickly became a popular addition to the range. Today, as around one in four oil boiler installations are external, Grant have expanded the number of options available with the launch of three competitively priced Eco External modules. The models have outputs between 15kW and 35kW (50-120,000Btu/h) and SAP 2009 gross seasonal efficiencies of 90.3 - 90.8% gross.
Grant Vortex Eco External 15-21, 21-26, 26-35
External finish This high efficiency Eco External range has some unique features including multi-directional flueing options, high quality external powder coated paint finish, built-in boiler frost protection, mains isolating switch and a test switch.
Sealed system kits Eco External boilers can be converted to sealed system operation by purchasing a pre-assembled kit from Grant UK (Product code: VTXECOSSKIT35). The sealed system kit includes an expansion vessel, automatic air vent, pressure relief valve and circulating pump. A filling loop and pressure gauge are also supplied as part of the kit. These can be fitted within the module casing, or ideally in a convenient site within the building, located between the cold main and central heating return.

Grant Vortex Pro Combi range
Introduction
Dimensions (mm)
For almost two years Grant has been working behind the scenes on brand new electronic versions of the successful Grant Vortex Combi range with the aim of incorporating as many of the additional features and benefits customers have requested, whilst bringing the technology installed in these appliances up to the minute.
Grant Vortex Pro Combi internal 21e and 26e
The models now include internal frost protection, neon diagnostic indicators and a factory fitted internal condensate trap (this can be sited externally if preferred), which is designed to make installation and servicing easier. The Grant Vortex Pro Electronic Condensing Combi’s are available as internal or external models in three sizes, 21kW, 26kW* and 36kW.
Grant Vortex Pro Combi internal 36e
Unique designs Grant Vortex Pro Combi features much larger heat exchangers which, due to their low water content and larger surface area, vastly increase the hot water performance available and mixing valves are pre-set at 50°C, controlling accurately the hot water draw off temperature from the boiler. They also feature a low system pressure cut off switch, enabling the combi to protect itself in the unlikely event of system water loss. Additionally, there are two very accurate electronic temperature controls which allow the boiler to operate in condensing mode on central heating, whilst maintaining its instant hot water production.

Introduction
EZ-Fit flue systems
Grant Vortex oil-fired boilers are one of the most efficient heating systems on the market. We also have other products in our wider range that work in conjunction with the Grant Vortex to deliver even more efficiency and cost savings as well as increasing the environmental credentials even further.
All Grant Vortex oil-fired boilers are supplied for connection to either a ‘stainless steel’ conventional flue, or one of Grant’s EZ-Fit flue options. The flue systems are available as low level, high level or vertical kits, for internal and external applications, and even as unique EZ-Flexi packs, designed to enable condensing boilers to utilise an existing chimney. All our EZ-Fit flues carry the CE mark of approval, are adaptable to any installation, and deliver excellent value for money.
Making your system even more environmental Combining a Grant oil-fired system with a renewable technology like Grant Solar Thermal is an excellent way to keep fuel costs down and to ensure your household is as energy efficient as possible. Solar Thermal systems are easy to install, and when combined with our oil-burning systems could provide up to 70% of your hot water needs, reducing your fuel costs and protecting the environment too.

General information
Installation and commissioning
Standard Assessment Procedure (SAP)
Installation must comply with the current British Standards and The Building Regulations. Comprehensive technical information can be found in the installation manual, supplied with every boiler.
SEDBUK was developed by the Government alongside boiler manufacturers, under their ‘Energy Efficiency Best Practice Programme’. It was designed as a fair basis for comparisons of boiler energy performance when installed in a typical domestic situation in the UK.
As with all oil-fired appliances, Grant Vortex condensing boilers require commissioning at the time of installation. This simple process ensures that the boiler is working at peak efficiency which, in turn, will result in lower running costs and long term reliability.
Pluming Condensing boilers operate at extremely high efficiency levels, producing cool flue gas temperatures, resulting in a ‘plume’ of vapour being visible at the flue terminal. This plume (steam) is a normal condition of condensing boiler operation and indicates that the appliance is working efficiently.
To determine boiler efficiencies, a ‘Standard Assessment Procedure’ more commonly known as SAP, is used. SAP is the Government’s standard method for energy rating. SAP ratings enable the comparison of energy efficiencies and demonstrate the likely effect of improvements to a property in terms of energy use. Since SEDBUK was introduced in 1999, it has undergone many changes, the most recent being the move from SAP 2005 to SAP 2009. The changes focus on improving the accuracy of the way the efficiencies are worked out.
Low level balanced, high level, or vertical flue kits are available, which moves the plume to a higher level. Alternatively, it is possible to convert an existing low level balanced flue to an external high level or vertical arrangement using Grant’s Plume Diverter.
SAP 2009 incorporates a key revision in the assumed carbon emissions per kWh of oil used by the boiler. It may appear that the efficiencies of boilers have reduced with SAP 2009, but it is important to understand that the new methodology gives a more realistic estimate of the average annual boiler efficiency when installed in typical conditions, based on evidence from recent independent testing and field trials.
Guarantees
Fuel
The unique heat exchanger on Grant Vortex condensing boilers is covered by a 5-year guarantee. All other component parts of the boiler are guaranteed for 2 years from the date of purchase (excluding consumable items), subject to being installed in accordance with the manufacturers instructions. There are also optional annual, or 3-year extended warranty schemes available. On completion of the installation all Grant Vortex condensing boilers must be commissioned and the guarantee registration form completed online.
The burner on all Grant Vortex boilers is supplied factory set at the stated output for use on standard grade kerosene - Class C2. Grant Vortex condensing boilers manufactured from May 2011 onwards, however, will have a new ‘bio compatible’ burner fitted which is also suitable for biokerosene at a 30% blend, known as B30. To use B30 fuel, it will be necessary to change the oil feed line and ensure that other components used during installation e.g oil tank, etc. are suitable. Grant Vortex condensing boilers must not be used with Class D gas oil.
Aftersales service For peace of mind, all Grant central heating boilers are backed by a national network of independent service engineers. In the unlikely event of a problem occurring, your installer should telephone our Customer Service Department on: 01380 736920.
